To all whom it may concern.-

Be it known that I, WILLIAM HORSEFIELD, of Morristown, in the county ofMorris and State of New Jersey, have invented a new and Improved Ladder,of which the following is a full, clear, and exact description.

My invention relates to an improvement in ladders designed moreparticularly for painters use for supporting a scaffold alongside of abuilding; and the invention consists, principally, in combining with theladder a screwrod to pass through the side pieces of the ladder andenter the side of the building to hold the ladder in upright position.-

The invention also consists in forming the ladder with side projectionsto space the ladder-from the side of the building.

The invention further consists of the construction, arrangement, andcombination of parts, all as hereinafter describedand claimed. Referenceis to be had to the accompanying drawings, forming a part of thisspecification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 shows the application of the ladder to the front of a building.Fig. 2 is an enlarged detailed perspective view of the cen: tral portionofthe ladder, showing two sections spliced together; and Fig. 3 is adetailed side elevation of the same.

A represents an upper and B a lower section of the ladder. These areeach composed of the two side pieces, a a, and the rungs b b,

The side pieces, a a, arejointed together by the lap-strips a a, theends of which are notched, as shown at a of, to engage with the rungs cc, which are by preference made square or rectangular in cross-section,so that when the two parts of the ladder are united the said rungs willact as locks to the respect rungs.

through to one side of the ladder, as shown at ive sections. The rungs bare common short The rungs a are elongated and reach 0 to hold theladder away from the building, as illustrated in Fig. 1. The rungs c arealso elongated, as shown at c, for the same purpose.

Through the lap-pieces a a of the sections of the ladder are holes (I,for the passage of the rod 0, which is headed at its outer end andformed with a screw-thread at its opposite end to enter the side of thebuilding for securing the ladder thereto for holding it securely inupright position.

When two ladders are put in position and made fast by the rod 0,scaffolding-boards may be placed from ladder to ladder upon the rungs,and they may be easily raised from rung to rung or lowered, as desired,and the extensions 0 c furnish working-space between the ladder and thebuilding. In this manner the ladder or ladders serve the double purposeof supporting scaffolding and furnishing ready means for ascent anddescent to and from the scaffold.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with a ladder, of thescrew-rod 0, passed through the side pieces of
